CARTON.

Specification of Letters Pat ent. Patented Aug. 19, 1913.

Application filed April 6, 1912. Serial No. 688,834.

' the following specification.

This invention relates in general to receptacles of various types, and more particularly to receptacles adapted to be used for marketing various articles or substances which are required to be kept hermeticallysealed until such time as they'are to be used.

The invention will be hereinafter discussed in connection with cartons adapted to contain aseptic bandages, absorbent cotton and the like, although it will be understood that the invention may be embodied with equal efficiency in receptacles of numerous shapes and forms intended for a wide variety of uses. In the preparation of aseptic bandages, absorbent cotton and the like for the trade it is desirable that such articles be sterilized afterthey have been placed in the cartons in order that they may not be handled between their sterilization and the time of their use. It is, moreover, particularly desirable that the receptacle containing articles of this sort be hermetically sealed immediately after sterilization to eliminate as far as possible the danger of contamination by exposure to the air.

It is a principal object of .this invention to a provide a carton that may be sealed quickly andwhich will require a miniand easily 7 the performmum amount of handling in ance of this operation. x

A further object of this invention is to provide receptacles of the character described with a sealing means which will be simple and cheap 'to manufacture and which will efiiciently seal the receptacle. I

A further object of the invention is to provide simple and efficient means to unseal the receptacle when it is desired .to use the contents thereof.

Further objects and advantages of the invention will be apparent as it is better understood from the following description which, taken in connection with the accompanying drawings, illustrates two preferred embodiments thereof. a

011 the drawings Figure 1 is a perspective showing a car ton provided with various features of my in vention; Fig. 2 is a plan view of a. blank showing a preferred form of the sealing sheet; Fig. 3 is a perspective view of the carton shown in Fig. 1 before the sealing sheet has been applied; Fig. 4'is a perspective View disclosing a modification of the carton shown in Figs. 1 and 3, and Fig. 5 is a View similar to sheet hasbeen applied.

From the drawings it will be observed that the receptacle employed to illustrate the two preferred embodiments of the invention hereinafter described is composed of rear and bottom walls, a front wall 10, end walls 11 and a lid 12. along its 'rear edge to the rear wall of the receptacle, the whole being formed of a sin -gle blank of cardboard in accordance with the method usually employed in the construction of cartons intended to contain bandages, absorbent cotton ard the like, although it will be obvious that various forms of receptacles may be employed with equal efficiency. The end walls 11 are preferably extended beyond the top of the carton to;

form flaps 13 which may be folded inwardly and disposed beneath the lid when the carton is closed. The front edge of the lid 12 The lid is flexibly secured- Fig. at before the sealing is preferably extended beyond the front wall 10 and folded downwardly as at 14 to form the flap 15 to be inserted Within the carton between the front wall 10 and the front edges of the inwardly extending flaps 13 to close the carton. In this form of receptacle it. is therefore only necessa ry to seal three edges, the remaining edges being hermetically secured together by gluing or otherwise securing in any other suitable manner the adjoining edges of the blank. To properly seal the said three edges I provide the blank 16 as shown'in Fig. 2. This blank is preferably composed of a single sheet of paper or other readily severable material consisting of the main elongated portion 17 and the integral portion 18 disposed partially along one side thereof, the length of the portion 18 being substantially the length of the carton. The elongated portion '17 is extended beyond the portion 18 to form the end portions 1%), the width of the-portion 17 being substantially the width of the carton.

To seal the carton after the contents have been positioned therein and sterilized if desired it is only necessary to paste or glue the blank 16 to the receptacle as disclosed in' dim-A Fig. 1, the blank being disposed over the top of the receptacle, the end portions 19 being folded down over the ends thereof and the portion 18 over the front wall whereby the open edges between the lid and body are effectively sealed. To unseal the receptacle 1 provide a cord 21 adjacentthe adjoining edges of the said lid and body of the carton. An end of this cord is fastened to the carton and it may be retained in position about the edges to be unsealed in a number of ways, two of which will be hereinafter described. As is seen in Fig.

3 one end of the lid is slit transversely be-' tween the sides as at 22 and a. second slit 23 is provided at the junction of the lid and the body of the carton. The end 21 of the cord is inserted in the slit 23, then laid back over the said lid and inserted in the slit 22. If it is desired the end of the cord may be further secured by inserting the said end again in the slit 23, although the said slits will efiectively retain the end of the cord by grippingit at the firsttwo points alone.

At the ends of the junction between the lid 12 and the flap 15 are formed the slits 24 and 24, and a similar slit 25 is provided at the end of the junction between the lid 12 and the rear Wall of the carton. The cord after being secured at its end to the slits 22 and 23 is brought to the front of the receptacle beneath the cover and engaged by the slit 24, thence outside the said lid and along its junction with the flap 15 to a the slit 24 at the other end of the said lid,

and thence rearwardly beneath the cover where it is retained injpositionby having the free end 26 inserted in the slit 25. It will thus be manifest that the cord will be firmly secured in position and that the sheet of material sealing the said carton may be readily severed along the desired edges by merely grasping the free end 26 of the string and causing it to tear the said sheet as is shown in Fig. 1.

Figs. 4 and 5 illustrate another method of retaining the cord which consists in inserting it in the slits 27 and 28 which are analogous in every respect to the slits 22 and 23 hereinbefore described, serving as did the slits 22 and 23 to secure an end of the cord.

inmate Tn this form, however, the cord 29 lies without the receptacle at the ends as at 30 and within the receptacle behind the front wall 10 as at 31, being retained in position by v the slits 32 and 33 formed at the top of the junctions between the end and front walls. The free end of the cord 33 is secured in a slit 34 similar to the slit 33 formed at the end of the junction between the rear wall and the lid. In this form the free end 35 of the cord may be removed from the slit 33 and pulled to sever the sheet 16 as is shown in Fig. 4:.

It is manifest that the cord may be positioned either before or after the carton receives its contents, as the said cord is maintained in position independently of the position of the lid. When the carton is constructed to contain aseptic bandages, absorbent cotton and the like, the cord may be positioned before sterilization, thereby permitting the carton to be sealed ately after sterilization in an appreciable period of time by merely pasting or otherwise securing the sealing sheet as hereinbefore described.

It is manifest that numerous changes may be made in the form of the slits and their location, as well as in the form of receptacle and sealing means, without departing from the spirit and scope of my invention, or sacrificing any of its benefits, the forms hereinbefore disclosed being merely two preferred embodiments thereof.

T claim A carton comprising a body, a lid therefor, said lid having a portion at one end set ed by slits, a sheet of readily severable material disposed over and secured to adjoining edges of said body and lid when the carton is closed to seal the lid to a side of the body, and a cord disposed beneath the said sheet adapted to sever the same to unseal the carton, an end of the said cord being wound about said set-oft portion of the lid and secured in position by the said slits, each of said slits positively gripping the said cord.
